<p>The present invention provides a self-healing method for processing a composite web services process, said composite web services process invoking at least one elementary web service. The method comprises the steps of: providing the elementary web service with at least one alternative web service, which is independent of said elementary web service and implements the same function as that of the corresponding elementary web service; parsing the model definition of said composite web services process to search the steps that activate the invocation of the elementary web service; inserting healing logics after said steps that activate the invocation of the elementary web service, which are searched from the model definition of said composite web services process. And during the procedure of executing said composite web services process, said healing logic detecting whether the previous invocation of the elementary web service is failed or not, and in the case of detection of an invocation failure, said healing logic invoking said alternative web service corresponding to the elementary web service which failed to be invoked. ® KIPO & WIPO 2007</p> |
